Many galaxies are too faint or small for us to observe easily – but science can help us work it out.
After its fourth delay, the Artemis 1 launch is now scheduled for Nov. 16, 2022. NASA has a history of missing launch deadlines, but the private sector is slowly making launches more reliable.
The Double Asteroid Redirection Test successfully showed that it is possible to crash a spacecraft into a small asteroid and change its orbit. This technique could save Earth from asteroids in the future.
The meteorologist leading NOAA’s 2022 hurricane field program describes flying through eyewalls and the technology in these airborne labs for tracking rapid intensification in real time.
The Double Asteroid Redirection Test successfully showed that it is possible to crash a spacecraft into a small asteroid. Whether the approach could save Earth from a future threat remains to be seen.

We don’t know much about the target asteroid of Nasa’s imminent Dart mission, so it’s hard to predict what will happen when we crash into it.
Crashing the 1,340-pound DART probe into the small moonlet orbiting the asteroid Didymos should redirect its trajectory – and could be a model for how to save Earth in the future.
Discarded pieces of landing gear, crashed spacecraft and wear and tear have produced a lot of debris that is now scattered around the Martian surface.
Newly discovered super-Earths add to the list of planets around other stars that offer the best chance of finding life. An astronomer explains what makes these super-Earths such excellent candidates.
